可见光面目标反舰导弹探测用于指挥火炮系统对逼近的反舰导弹进行跟踪射击。采用图像差分和小波变换可以准确提取信噪比接近于1的反舰导弹图像,通过特征一致性评估算法以及基于对运动轨迹一元线性回归效果的检验进一步对该反舰导弹图像进行判断。试验证明,提出的目标提取算法和探测算法可以在近距离用可见光图像探测与背景灰度接近的反舰巡航导弹目标,也适合于其他来袭导弹与飞机的近距离探测,具有较普遍的探测适用性。
Visible surface anti-ship missile anti-ship missile detection command system for artillery approaching anti-ship missiles for tracking shooting. The image difference and wavelet transform can accurately extract the image of anti-ship missile with a signal-to-noise ratio close to 1, and further determine the anti-ship missile image through the feature consistency assessment algorithm and the test based on the univariate linear regression of motion trajectory. Experiments show that the proposed target extraction algorithm and detection algorithm can detect the target of anti-ship cruise missiles close to the background gray level with the visible light image at a close range, and are suitable for the short-range detection of other incoming missiles and aircraft with the more common detection applicability.
